Bomb squad says the materials were being used to manufacture fire bombs or make explosive materials.

Two students under the age of 21 have been arrested on drug and alcohol-related charges. A third person was also charged with drug and alcohol-related offenses and possession of bomb-making materials. Police have not identified the suspects at this time.

George Mason Police released a statement that said:

“On Wednesday, March 16, George Mason University Police received a report of flames being shot out of a window in Jefferson Hall.

When police arrived, they found sufficient cause to request a search warrant for possible drug paraphernalia. On Thursday, March 17, police obtained a search warrant and found drug paraphernalia as well as items consistent with the production of a dangerous device.

Three students were arrested: two on drug and alcohol related charges and one charged with possession of bomb making materials. Search warrants said police discovered a leafy green substance, match books, shaved match heads, a mortar and pestle, lighter fluid, hand sanitizer candles and a PVC pipe inside the dorm.

Officials reported the items could be combined to make explosives.

FOX News reports that the bomb squad later advised campus police that the materials were being used to manufacture fire bombs or make explosive materials.

Students, some of whom live in Jefferson Hall say they are disturbed by this, but are relieved the materials were discovered before someone got hurt.

“It’s surprising to me that no one else on the floor knew about it, and if they did, they didn’t say anything about it,” said student Sydney Cono. “Explosive are very, very harmful, but at least the police caught it before something bad could have potentially happened.”

George Mason University’s Office of Strategic Communications has declined to identify the individuals.
